Tammi is a lemon yellow monkey with dark gray-tipped feet, hands, and ears. The inside of her ears are hot pink, and she has a black and white-striped tail. She has dark gray rings around both eyes, each with a single eyelash, and she has small black pupils and red irises. Though Tammi is a monkey, her appearance bears resemblance to the ring-tailed lemur, despite her name possibly referring to the Tamarin monkey. Tammi initially wears a New Spring Shirt.
Below is a brief description of the peppy personality. For more information, click here.
Peppy villagers appear to be in a good mood often, and are easy to become friends with. As a peppy villager, Tammi will have the tendency to over-react in conversations about trivial subjects, and will usually be over-excited to see the player or other villagers. This villager, like other peppy villagers, will rarely be discouraged from doing anything, including the usual hobbies. Peppy villagers dream of becoming famous in the future and read Ms. Nintendique, an unseen magazine read by snooty, normal, and other peppy villagers in the Animal Crossing Series. Peppy villagers will also have a very short attention span, which means they soon forget some arguments or tasks given to the player which were not completed. Tammi may easily get upset in conversation when wrong things are said. She will get along well with other villagers, particularly the lazy, normal, jock, uchi, other peppy villagers, but she may annoy and upset cranky and snooty villagers, whose personalities differ. Due to the nature of peppy villagers, she may mention how "old" or "boring" cranky villagers are compared to her opposing, upbeat personality.
In Animal Crossing: New Leaf, Tammi's house now resembles a restaurant and uses the exquisite wall with the shanty mat for wallpaper and flooring. She has many items from the Exotic Series: two chairs, a bench, a table, chest, an end table, and a lamp. She also has two lazy-susan tables in both far corners of her house, a lady palm, a birdcage, and a phonograph that plays Imperial K.K..
